Features the product and filter properties of the LARYVOX^® EXTRA HME. The filter medium integrated in the LARYVOX^® MY EXTRA HME housing serves for exchanging heat and moisture and filters the respiratory air. Due to the loss of nasal breathing, filtration, warming and humidification of the respiratory air must be ensured in order to prevent irritation of the airways due to dry air, dust, or harmful substances contained in the respiratory air. After surgery, tracheotomised/laryngectomised patients often suffer from increased production of mucus and irritation of the airways associated with an urge to cough. These symptoms can impair breathing and voice rehabilitation. Regular use of HME filter cassettes alleviates the symptoms through reduction of viscous secretions in the lungs and promotes pulmonary rehabilitation. LARYVOX^® MY EXTRA HME can be worn both during the day and at night.
There are four different filter variants for different needs:

• NORMAL – Normal breathing resistance for situations requiring normal physical activity
• MEDIUM – Breathing resistance for physical activities
• HIGHFLOW – Reduced breathing resistance for situations with strong physical exertion
• SPORT – Very low respiratory resistance specifically for sporting activities
